I looked it up before buying one and basically I understood it to be that you have to open it by your own power a certain distance before the spring takes over.... Called "assisted open" or something. I carry a small one in my purse..... As long as the first couple millimeters is manual I understood it to be legal.

Im going to call the Sheriff's Dept. tomorrow and ask. The PSP doesnt know and I need to be 100% sure. I dodged a potentially serious legal issue in 2013 and I dont want to chance a legal problem. I will let you know what I find out.
